To dll whom it may. concern:

Be it known that I, JOHN WILLIAM CARR, a subject of the King-of Great Britain and Ireland, and resident of Manchester, in the county of Lancaster, England, have invented new and useful Improvements in Weft-Rel .plenishing Looms, of which the following is a transferred from a magazine to grippers on a' specification. Y

This invention relates to improvements in that kind of lling' replenishing apparatus for looms in which a cop on a cop carrier is rocking plate, which on the failure of the filling in the shed is operated by means of the filling fork so as4 to turn the grippers from a vertical into a horizontal position, so that when the slay beats up the new cop is pushed into the shuttle from the front and the spent cop pushed out at the back thereof, for which.

an application fora atent has been fled'by me and another in t e United States Patent Office on August 26th. 1904, Serial 'No 222357. 'I

The improvements consist chiefly in the constructive arrangement of the magazine or hopper from which the fresh cops supported by spindles fixed in carriers or blocks are su plied as required, in combination with mecfianism for advancing the cops after each change and inserting a' fresh cop into the grippers on the rocking plate, and for operating said rocking plate so as to bring'the cop in the grippers into the position required for inserting it into the shuttle andgejecting the spent cop.

On the drawing attached hereunto, Figures 1 and 2 represent side elevationsl of the I Vmagazine; Fig. 3 a front elevation of the same; Fig. 4 a side elevation of the loom with parts omitted andshowing the ma azine in position; Fig. 5 a planof part of theoom, Figs.

6 and 7 several views of the means for carryv ing the cop spindles 'in the magazines g Figs. 8,

9 and '10 several views of the shuttle box,

-means for transferring the copl spindles from the magazine to the shuttle and spent cop and spindle chute, and Fig. 11 a si e elevation of the shuttle with the cop and spindle in position.

In the improved apparatus illustrated, the copsv 1 are carriedv bycop spindles 2,L fixed each at one end in a block 3 of rectangular cross section, see Figi 11," and these blocks ft into the shuttle as hereinafter described.

l curing the end of the thread of In the magazine, the spindles are keptpseparate from one another and are gripped 1n carriers by'y which they are advanced. These carriers consist eachof a bar 4, Figs.v vand 7, provided with a sprin .jaw 5 at one end, and a saddle su port 6 in ie center and a stud or hook 7 at tlie other end for the puurpose of set e cop. The

ends of the carriers are provided with projections 8 adapted to slide in curved grooves and to form units of a rack and the projections are preferably formed as round pins as shown and they may be furnished with rollers. The magazine consists of an endless apron formed of the bars 4 which lie together longitudinally, p

rovided with endless grooves 11 upon their inner faces into which grooves the ends of the lprojections 8 ofthe bars 4 engage. These projections enter into the grooves 11 only for a portion of their length, sufficient space being left between the sides of the frame and the ends of the bars for the teeth of a wheel for advancing them, tok engage. The side frames are preferably formed in sections' to facilitate the machining of the grooves and f or this purpose the two ends 12 a're formed and two side frames 9 and 10 semi-circular and thecenter part 13 rectangular with straight parallel grooves therein, the sections being Joined together bythe bolted flanges 14 and the transverse boltl5.

Each frame is formed with a foot 16 'whi'hv can be bolted to a bracket 17 fixed to the loom frame.

The two side frames carry a shaft 18 in bearings formed this shaft are fixed two sprocket wheels 20 and 21 the teeth of which are so `formed and pitched as to engage between the proj ectionsv outside the frames are fixed at one side a wheel 22 with indents of the same anitch as that of the sprockets into 8 of the carriers 4.. Upon thesame shaft scallop gular. which Indents bears a-spring fixed to the side of the'frame at 23, and at the other side a ratchet wheel 24.

in the bosses 19, and upon The side frames also`carry two ears 25 and 26 having bosses forming bearings for a rocking shaft 27. This shaft carries means hereinafter termed gripper for receiving a cop spindle and presentingthe same in the path of the shuttle 'box so that when the weft has given out in the shuttle, the forward motion of the slay forces the spent eop spindle vthrough the shuttleby contact with the spin- 11 at the outer end of the s indle block 3,v

andat the other side also wit a slot 30, Fig. 2 into which the spindle enters, a springg31 bearing against the block so that it is gripped in its proper position in the standard. A cradle'32 adapted to su port cops of various diameters and adjusta le in a standard 33 fixed on the rocking shaft 27 is used, the end of the spindle being left free to allow the weft to be freely drawn off it. The rocking shaft is turned a quarter turn on the failure of the weft by means of al vertical rod actuated by a A cam, and, as before stated presents the cop spindle to the shuttle when in the shuttle box, in pro er position to be inserted in 'they shuttle, as s own by Fig. 4.

To secure the cop spindle in its longitudinal position in the shuttle 34, the block 3 is provided on its underside 35 with a series of grooves and a plate 36 provided with corresponding projections is fixed inthe shuttle which grooves and projections engage with each other and thus hold the spind e 1n position and it will be clear that the longitudinal position of the spindle relatively to the shuttle may vary. Above the spindle block .3, Fig. 11, in the shuttle, asprin'g finger 37 is fixed which allows thecop spindle to be pushed in from the front and out at the back. lhe shuttle box front 38 is provided with a slot as shown on Fig. 8 and the back with a slot 39, throu h which the spent cop spindle is forced an afterwards it falls into an inclined chute 4() and is delivered into a skip at the side of the loom.

With an apparatus changing the cop spindie it is necessary to provide the apparatus and shuttle with a self threading arrangement andany suitable known one may be used. For the purpose of facilitating the threading of the shuttle and for. supporting and carrying forward the ends of the thread of the cop, lI propose to use the following As before stated, the ends. of the threads of the oops are lapped on to arrangements.

studs or hooks 'Z of which there is one for every bar or unit of the apron. These hooks -7 place, at each change, the thread from the cop transferred to the gripper 28 into the forked end of an arm 41 which is fixed on the rocking shaft 27. When the gripper 28 1s turned into a horizontal position to transfer the cop to the shuttle, the weft thread between the spindle tip and the hook 7 is turned with it and held in the direction of the cop spindle in front of the slay. As the latter beats up, the thread passes behind a hook 42 Figs. 4, 8 and 9 fixed to the slay beam in front of the shuttle box over a ledge 43 and under a projection 44 so as to be held in front of the shuttle. `When .the shuttle is picked after the change of cops, the weft thread being held by the hook 42 and its attachment to the hook 7, along the shuttle osition for engaging with a front, is in a suitable threa ing device on the shuttle.

The rocking shaft is turned on the failure of the weft in the shed by a vertical rod 45 Fig. 4 and which-is connected to an arm 46 on the said shaft and moves in a guide 47 fixed to the frame side and its movement is limited by adjustable stops. The rod is carried by a pin 48 passing through the said arm and is supported by one end of a lever 50 fulcrurned upon a bracket 51. The other end of the lever carries abowl 52 which by the movement of the weft fork carrier on the failure of the weft is shifted'so as to engage with a grooved cam 53 fixed on the tappet shaft 59 of the l'oom. Preferably I fix the lever 50 on a shaft 55 adapted to slide longitudinally in its bearings in the bracket 51 fixed to the loom frame, and connect this shaft to the weft fork carrier by a chain 56 passing over guide pulleys or by equivalent connections so as to vbe pulled by the weft fork carrier against the ressure of a spring brought upon an unshrouded part 58 of the cam 53 and entering the groove, lifts the rod 45, holds it in its highest position while the slay beats up and the change of cops is effected, and then moves it down again, until when the bowl reaches the unshrouded part 58 of the cam again, the lever 50 is pulled sidewise by the spring 57 and the parts come to rest till the next change. To prevent the lever from being pulled sidewise as soon as the weft fork is released, a flange 60 is cast on the cam, which retains the bowl till the downward movement of the lever is com leted.

T e rod 45 is as stated connected near the top to an arm 46 fixed on the rocking shaft 27 and as therod is moved upwards by the cam, the rocking shaft is turned by a uarter turn and places the gripper into a vorizontal position, so that when the slay beats up, the cop is transferred to the shuttle'.

To advance the sprocket wheels and carriers by one division after each change of cops, the ratchet wheel 24 Figs. land 3, has a itch of teeth to correspond with the wi th of the carriers forming the apron. A three limbed bell crank lever 61 is mounted loose on the shaft 18, one limb carrying a pawl 62 which engages with the ratchet moved upwards by the cam, .a projection 63` adjustab y fixed to its end comes against the second limb 64 of the bell crank and moves it back, till the pawl engages with the next tooth. The third limb 65'supports in a slot in its end, a pin passed through` a finger 66,

which is supported at its outer end on a stud or its equivalent fixed in a bracket 67, the stud passing through a long slot in the finger. When the bell crank lever is turned bythe rod 45, the limb 65 moves the finger 66 forward, and at the same time a projection 68 Fig. 4 on the rod 45 raises the finger up as shown so that it passes through a slot ina plate 69 fixed to the front of the slay whenthe change of cops is effected by the beating up of the slay. Before the next beat occurs the rod 45 has descended again and the finger 66 has dropped down into a slanting position, in which it is encountered by the plate 69 at the beating up of the slay and pushed to the front. Thereby the bell crank is turned by its limb l65 and the pawl advances the ratchet by one tooth and the `apron by one division, whereby a fresh cop is inserted into the grippers, which have returned to their vertical position as the rod '45 is pulled down by the lever 50 and the cam 53, and the apparatus is ready for the next change.

The apron is held in position while the awl moves back by the scallop wheel 22, ig. 2, which has the same number of indents as the ratchet wheel has teeth, and a spring 7 0 fitting into the scallops is fixed to the side frame l0.
